I have been having intermittent problems for the past month or so. I signed up in November and had no issues until my number got ported over. Then they began. I have been having choppy / garbled calls. Most of the time not bad, but very noticeable. syllables are missing from words not to the point where it cannot be understood, but enough to be very annoying. Some days / times are much worse than others. (95% of the time the party I am calling says I sound fine, it is only what I hear that is the problem). There is also often times hiss or white noise in the background when no one talks - but mostly on outbound calls only).

Here is the weird part; when I called Vonage tech support, that sounds perfect. The hold music was clear, no drop outs, no hiss, no crackle, no garble, etc. But when the call me from an outside line or I call them back at a 1-732 number, the crackle, choppy, etc comes back.

I have an open ticket with them, but have not heard anything yet, (It is from Tuesday). I called today and they say they are still analyzing the data.They mentioned that the calls to Vonage are in network, so the don’t go outside. But, my Dad has Vonage too, and I get the garble when I call him, so that is an in network call, so I don’t know what is going on.I called a friend who has Optimum Voice from Cablevision, he sounded fine. No garble.Any ideas?Below are the test my Voip results.ThanksTO BOSTONMedia Quality MOS 3.9 / 5.0(Best with G.711 is 4.4)

You're getting mixed results on your Voip test, and the second set has sufficient dropped packets to explain the sort of symptoms you're having. Try removing the Vonage device for awhile and repeating the test a few times. Are the scores consistently better?

I redid the test twice, pc plugged directly into modem.What I don't understand is why when calling Vonage tech support or getting calls from them it sounds fine, but when they call on an outside line or I call anyone it is bad.

Would the problem be somewhere after the call leaves Vonage and connects to the old phone company?

Since you only had the modem connected to the pc and you had intermittent burst loss from Jitter delay, Call the cable company. When they check the network it stands to reason they might not see the problem because the Jitter numbers intermittently go up and down between tests (ave are low but the max shouldn't go over 100ms). And burst loss is no good for any Voip company. That would explain dropped words and such. When you call don't tell them you use Vonage. Tell'm your gaming is no good or something. I would also not have the Vonage device hooked up when you call. I'm not saying that Vonage doesn't have something to do with it but eliminate the cable end of it. By the way are you using a 2.4 wireless phone with your calls? You've got good up/down load speed numbers. But, when the problem calls happen, what are the modems numbers for Download/SignalToNoise/Upload power numbers from the 192.168.100.1 signals page?

Try turning off the radio of the wireless on the BEFW11S4. And separate the routers (as much as possible) into dif parts of the room. And make some calls. Don't use a 2.4 phone if that's what you were using.

I see there are some major diferences, but the biggest one that bothers me is the 5th one. Power level. Yours looks low, as that should be a negative value. Maybe disconnecting the modem and calling the cable company to do a line test is the key here.

Higher order QAM can deliver more data less reliably than lower-order QAM. So navydavy2001's numbers look to me to be excellent. QAM256 and 35dB SnR, and -2dBmV(I'm envious) . Figuratively speaking, too much power (high) and the modem blows up. And too low, the modem shorts out. But jml1124's SnR numbers are also ok but the QAM64 tells me that there are enough packet discards or loss that it doesn't support QAM256. 39dB is good for QAM64. But QAM256 can support higher speeds and volume. From what I can tell it's like the diff between a 2in fire hose(high pressure and speed with low water loss) and a 1/2in garden hose(low pressure and speed with lots of leaks). To that end I don't know if Optimum Online will agree that there may be a problem, because the garden hose is sort of working. Voip is better on a firehose than a garden hose.And QAM256, 64 or PSK is autoranging for the SnR. I don't believe you can't set it.ps.You didn't answer my earlier post(2.4 phone)(turning of radio)?
